The goal of this project was to begin development of a geopmorphic-based model that could serve as a decision support tool to help in developing strategies for archaeological inventory. Objectives of the project were to (1) identify relations among archaeological site type and landform type, landform age, geologic parent materials, active and inactive springs, and active faults; (2) integrate the geology, hydrology, and tectonics to determine the age, origin, and spatial distribution of different geopmorphic features; and (3) develop an archeological favorability map based on the integrated geology, geomorphology, springs, and active faults. Integration of geomorphic map analysis with field based studies of natural surface and subsurface exposures of Pleistocene and Holocene alluvial and eolian deposits is essential. The project evaluated existing geologic maps for Death Valley NP as a basis for assessing the geomorphic context of archaeological sites for modeling purposes. Comparison of available geologic maps at scales 1:250,000; 1:100,000; and 1:50,000 indicates insufficient map detail of critical Holocene-age landscape components to develop a geomorphic-based model. A small area was mapped at 1:10,ooo- and 1:30,000- scales and compared to the smaller-scale maps to demonstrate the degree of information loss relative to archaeological associations with landscape. Developing detailed geomorphic maps at about 1:6,000- to 1:8,000- scales using of 1m-3m LiDAR data would provide sufficient information to develop a viable geomorphic-based archaeological favorability model.
